To all whom it may concern:

Be it known that I, GEORGE W, FREELAND, a citizen of the United States,residing at Moline, in the county of Rock Island and State of Illinois,have invented certain new and useful Improvements in Apparatus forDelivering Coal and other Materials, of which the following is aspecification, reference being had therein to the accompanying drawing.

This invention relates to mechanism for measuring and dischargingmaterial, and has reference more particularly to the discharge of coalinto locomotive tenders, from storage bins, chutes and the like. Suchstorage bins are usually arranged at the side of the railway, track andare supported with their bot tom somewhat elevated above the track, sothat the coal will flow into the tender, suitable means being providedby which the engineer or attendant may control the discharge.

In accordance with the present invention, means are provided wherebysuccessive charges of material of predetermined and known weight aredelivered, the delivery of these charges, after the operation has oncebeen initiated, being automatically efiected, and continuing until therequisite amount has been delivered, whereupon the operation may bearrested.

More specifically my invention comprehends the employment of a chargedelivering device situated in the mouth of the storage bin and operableto receive a predetermined amount of coal and to discharge the same,said operations being automatically con trolled by the weight of thecharge, in such manner that the coal flowing into the charge deliveringdevice will be automatically delivered therefrom continuously insuccessive charges of predetermined weight. The charge delivering deviceis preferably in the form or a box or receptacle, provided at oppositeends with suitable closures, so operatively connected that when oneclosure s open, the other will be closed, and the said receptacle is somounted that it may be moved up and down at its discharge end, thedownward movement operating through suitable means to open its dischargeend and close its receiving end, and its upward movement operating toclose the discharge end and open the receiving end. The receptacle is soheld in its upper receivuing in succession and belng controlled by theweight of the charge.

I prefer to employ two receptacles 00- operatively connected together insuch manner that when one moves down to discharge its load, the otherwill be positively moved up to receive its load by the weight of thedownwardly moving loaded receptacle, the result being that onereceptacle will be receiving its charge while the other is dischargingits charge. But my invention is applicable as well to the employment ofa single receptacle, in which case the function of the loaded receptaclein raising the empty one, will be effected by a weight or equivalentmeans, so disposed and arranged as to be overcome by the downwardlymoving loaded receptacle, but acting to raise the same to its receivingposition after its contents have been discharged.

Locking means are provided for preventing the operation of themechanism, said locking means being adapted to be operated by theengineer or attendant to release the mechanism to permit its automaticoperations as described.

Means are also provided for making a record of the number of chargesdelivered by the receptacles, and for making a recordof the particularlocomotive to which the coal is supplied. 7

Further, means are provided for preventing the operation of themechanism except by persons authorized to operate the same, all of whichmechanisms will be fully described in the accompanying specification,and the novel features of which will be pointed out in the appendedclaims.

In the accompanying drawings:

Referring to the drawings:

1 represents a storage bin or receptacle, which in the present instanceis shown supported at the side of a track by posts, at such elevationthat the coal discharged therefrom may flow into a locomotive tenderstanding on the track. The bottom of the bin slopes downwardly as at 2toward the front, at which point the bin is provided with two openingsor passages for the discharge of the coal therefrom, which openings areseparated from each other by a partition 6 as shown in Fig. 2 Situatedside by side in said opening are two charge delivering receptacles 3 and4 adapted to receive charges of coal from the bin and to discharge thesame therefrom. Each of these receptacles comprises upper, lower andside walls, connected together at their edges, thereby forming a hollowreceptacle, rectangular in cross section and open at its opposite ends.The receptacles extend at a downward inclination with their rearreceiving ends in communication with the bin opening, and they arepivoted at their rear lower edges on a horizontal transversely extendingbar 5 fixed to the bin framing at the lower edge of the opening therein,the arrangement being such that the receptacles may be swung up and downon their pivotal axes, the forward discharge ends moving up and down insuch actions, and their rear upper ends swinging back and forth betweenvertical plates 6 fixed to the bin framing at opposite sides of eachreceptacle. These plates serve to guide the rear ends of thereceptacles, and they prevent the weight of the coal from spreading orbulging the side walls of the same.

The rear receiving end of each receptacle is provided with a swinginggate or valve 7 which may be swung up across its receiving end to shutoff communication of the receptacle with the interior of the bin, orswung down to open the rear end of the receptacle. This gate is in theform of a curved plate, fixed at its lower corners between two levers 8,which extend forwardly at opposite sides of the receptacle and arepivoted between their ends to hangers A on the bin framing, onhorizontal axes as at 9. The front discharge end of the receptacle isprovided with a door 10, pivoted at its lower end as at 11 to the frontedge of the bottom wall of the receptacle and adapted when swungupwardly to close the discharge end of the receptacle, and when swungdownwardly to open the same. The door is provided with side walls 12which, when the door is swung upwardly to closed position,

will extend at the outer sides of the side walls of the receptacle, andwhich, when the door is swung downwardly to open position, will formcontinuations of the side walls, whereby the outflowing coal will beprevented from scattering. This door is connected with the levers 8 bymeans of two links 13 jointed at their lower ends to the door betweenthe ends of the latter as at 14, and pivoted at their upper ends to theforward ends of the lovers 8 as at 15, the arrangement being such thatthe door 10 and gate 7 will be operated in unison, the door moving toclosed position as the gate moves to open position and vice versa. As aresult of this arrangement, when the gate is open and the door closed asshown in Fig. 2, the coal from the bin will. flow into the receptacle,and when the gate is closed to cut off the further flow of coal, thedoor will simultaneously be opened and the contents of the receptaclewill be discharged therefrom.

In accordance with my invention, I propose to control the operations ofthe doors and gates of the receptacle by the weight of the chargeentering the same, so that each receptacle will measure of and dischargea predetermined amount of coal at each operation, and I propose to soarrange the mechanism that these operations will be performedautomatically and continuously after once being started. These objectsare effected by controlling the movements of the door and gate, by theup and down swinging movements of the receptacle on its pivotal axis,and in so connecting the two receptacles cooperatively that they will beswung up and down in alternation, the result being that after a load hasbeen discharged from one receptacle when the latter is swung down andits discharge door opened, it will be swung upwardly to a receivingposition by the other receptacle, which in the meantime has received itslead, and when this latter receptacle has discharged its load, it willbe raised again to a receiving position by the descent of the firstnamed receptacle, which in the interval has received another load.

The detailed construction for eifecting these operations is shown moreparticularly in Figs. 1 and 2, where it will be seen that the levers 8of each receptacle are connected to the bottom of the receptacle bymeans of links 16, the upper ends of which are jointed to the levers 8as at 17 at points forward of the axis 9, while the lower ends of thelinks are jointed to the bottom of the receptacle as at. 18. As aresult, when the discharge end of the receptacle swings downwardly fromthe position shown by full lines in Fig. 2 to the position indicated bydotted lines in said figure, the levers 8 will be rocked by the links ontheir axes O and their forward ends will swing clownwardly, and owing totheir connection with the discharge door, the latter will be swungdownwardly to open position, while at the same time the gate 7 will beswung upwardly to closed position, the operation of the door and gatebeing thus automatically efiected by the downwardly swinging movement ofthe receptacle.

The two receptacles are suspended at their front by means of twovertical suspending straps 19 and 20, the lower ends of which arepivoted as at 21 and 22 to the upper walls of the receptacles.respectively, which straps near their upper extremities are pivoted, asat 23 and 24 respectively, to the upper ends of a horizontal balance bar25 pivoted between its ends as at 26 to the front of the bin framing ona horizontal fore and aft axis. As a result of this arrangement, the tworeceptacles are so operatively connected together that when one is swungdownwardly, the other will be simultaneously and positively swungupwardly, the downward movement of one receptacle causing its dischargeend to open and its gate to be closed, and the upward movement of theother receptacle causing its discharge door to be closed and its gateopened.

It will be understood from the foregoing description that the receivingposition of the receptacle is when its discharge end is at the upperlimitof its swinging movement, in which position, the rear gate will beopen and the discharge door closed, as shown by full lines in Fig. 2. Inthis position, the coal from the bin may flow freely into thereceptacle, where it will be retained by the closed discharge door.

In order that when apredetermined amount of coal has entered thereceptacle, the weight of the same may cause the re ceptacle to swingdownwardly to eifect the discharge of its contents, 1 provide means fortemporarily holding the receptacle in its elevated receiving position,which hold ing means is adapted to be controlled by the weight of thecoal in the receptacle in such manner that when the weight of the chargereaches a predetermined amount, the holding means will be actuated, andthe receptacle released, whereupon it will descend by gravity anddischarge its contents. ()ne form of means for effecting this result isshown more particularly in Fig. 1, where it will be seen that each ofthe suspension straps is provided with a holding dog or latch 30pivoted. to it near its upper extremity on a horizontal axis as at 31,which latch is provided with a nose 32 projecting outwardly therefrom,and having a horizontal lower face 33 and an oblique face 34 joining theformer, the said latch being so mounted on the strap that it ma; reel:horizontally relatively to the same to a 'pose presently to bedescribed.

limited extent on the axis 31, for the pur The two latches are adaptedto cooperate respectively with two levers 85, pivoted between their endsto the bin framing on horizontal axes 36 respectively. Each of theselevers comprises a long horizontal arm 37 and a shorter downwardlyinclined arm 38, the pivotal axis of the said lever being at thejunction of these arms. A weight 39 is mounted on the arm 87 in suchmanner that it may be adjusted longitudinally thereof to and from theaxis 36, and the arm 38 is provided with a roller 40, the form, arrangement and construction of these parts being such that the weight willhold the level? with the roller 40 in the path of the latch. hen thereceptacle swings upwardly to its receiving position, the inclined faceof the latch will ride against the roller, and the latch will be rockedinwardly and le permitted to pass above the roller, whereupon it willrock back to its former position, and the horizontal face of the latchwill rest upon and be supported by the roller, whereby the receptaclewill be sustained in its upper receiving position. The size of the htsuch, and its relation to the a, of the lever so proportioned, that theroller will be held beneath the latch until the weight of the coal inthe receptacle reaches a certain predetermined. amount, whereupon thelower face of the latch acting on the roller will rock the lever on itsaxis, which action will move the roller outwardly out of the path of thelatch, thus releasing the receptacle so that the latter will swingdownwardly by gravity, and in such movement will automatically close therear gate and open the dischar the contents of the receptacle will bedischarged. The descent of the loaded receptacle will, owing to itscooperative connec tion with. the other receptacle, automaticallyelevate the latter, the latch of the ascending receptacle swinging onaxis in passing the associated roller, and when the re ceptacle reachesthe upper limit of its movement. the nose of the latch will be projectedabove the roller in a manner similar to the action of the latch.previously described. and the receptacle will be held by the roller inits upper receiving position, with the gate open and the front doorclosed. The coal from the bin will now flew into this receptacle, andwhen the weight of the same reaches a point where it will overcome theweighted lever, the latter will be rocked on its axis free of the latch,whereupon the loaded receptacle will descend and will discharge itscontents in .he same manner described in connection with the firstreceptacle, which latter will at the same time be automatically raisedto receive an ither charge. These operations being once started,

itw

door, d

will continue, with the result that charges of coal of known weight willbe auton'1ati cally delivered successively and continuously from the tworeceptacles alternately.

It will be understood from the foregoing description that the amount ofcoal entering the receptacles is dependent upon the size and location ofthe weights on the levers 35. ()rdinarily the receptacles are of thesize to hold each a ton of coal, and by a proper adjustment of theweights on the le vers, the receptacles will be held in their re ceivingpositions until the weight of the coal reaches a ton, whereupon theweight on the lever will be overcome and they will descend to dischargetheir contents. However, if it is desired that the receptacles dischargeless than a ton at each action, say half a ton, the weight is adjustedalong the lever and set at such position relatively to the axis of thelever that the weight thereon will be overcome when a half ton hasentered the receptacle, and the latter will be released. So also chargesof other sizes may be provided for by proper adjustments of thecontrolling weights.

In order that the engineer or attendant may control the operation of thereceptacles, that is, may initiate the operation when coal is to betaken from the bin, and may arrest the operation when the properquantity has been delivered, I provide means adapted to be operated bythe engineer and normally locking the receptacles against action, whichmeans are adapted to be actuated to release the receptacles and permittheir continuous operations as described. This locking mech anism in theform of the apparatus shown, acts on the weighted levers 35, andcomprises two movable stop rods 41 and 4t2 normally engaging the uppersides of the levers at their outer ends and acting to hold them againstmovement, but adapted to be moved free of the levers to permit the sameto be moved under the influence oithe weight of the coal in thereceptacles. These stop rods are pivoted at their upper ends onhorizontal axes 43, respectively, to the bin framing, the arrangementbeing such that the rods may be swung to an operative position withtheir lower ends in engagement with the upper sides of. the levers attheir outer ends, in which position of the parts the levers will beprevented from moving; or the rods may be swung clear of the levers torelease the same. The stop rods are adapted to be operated in unison,and for this purpose they are connected to a common operating member inthe form of an upright rocking lever 44: pivoted between its ends on ahorizontal axis to the bin framing as at $5. The stop rod ll isconnected to lever M by means of a horizontal link 46 jointed at itsouter end to the stop rod between the ends of the latter, and jointed atits opposite end to the lever below its pivotal axis e5. The other stoprod 42 is connected to lever 44 by means of a horizontal. link 47pivoted at its outer end to rod l2 between its ends, and pivoted at itsinner end to lever l i at the upper side of its pivotal axis 4-5. As aresult of this construction, when lever l4 is swung on its axis in onedirection, with its upper end moving to the right, the stop rods will beswung outwardly from their normal positions and will release theweighted levers 35 and will thereby permit the operation of thereceptacles; and when lever a l is swung in the opposite direction, thestop rods will be swung inwardly over the weighted levers and will lockthem against action. The operation of lever is in this manner iseffected by means of ropes or cables 48 and l9 connected respectivelywith the ends of the levers and extending downwardly within reach of theengineer or attendant at the ground level. The cable a9 is attached tothe upper end of lever 44 and passes over a guide pulley 50 mounted onthe bin framing and then downwardly to the base of the structure, theoperation of this cable serving to swing lever lt in a di rcction tolock the receptacles against action. The other cable lS is attached tothe lower end of lever at and passes over a guide pulley 51 mounted onthe bin framing and then downwardly alongside cable 49, and whenoperated it will swing the lever in a direction to release thereceptacles and permit their operation.

By means of the mechanism described, it will be understood that'when alocomotive tender is to besupplied, the engineer pulls on cable 48 torelease the mechanism, and the receptacle which had been held in anupper receiving position and into which the coal from the bin hadflowed, will be released, and it will swing down and discharge itscontents, the other receptacle at the same time being swung upwardly toreceive its load, and these operations will continue as heretoforedescribed,the two receptacles discharging alternately, charges of coalof predetermined weight. When the proper quantity has been delivered,the engineer pulls on cable 1-9, which will swing the stop rods inwardlyover the weighted levers, and the further operation of the mechanismwill be arrested.

Instead of employing two alternately acting receptacles as described,but one receptacle may be employed to operate continuously as shown inthe modified form of the apparatus represented in Fig. 8, wherein partssimilar to those of the form of apparatus previously described areindicated by like reference numerals with the exponent a added. In thecase of the two cooperating receptacles, the weight of the loaded receptacle in swinging downwardly, acts to T1 raise the empty one, In themodified construction employing but one receptacle, a weight 52 isemployed to lift the empty re ceptacle. This weight is mounted on theouter end of a balance lever 25 pivoted between its ends to the binframing on a horizontal axis as at 26 and pivotally connected at itsinner end as at 55 to the suspending strap 19 of the single receptacle3, below the latch 30 thereon. The weight, and the parts associatedtherewith are so proportioned with respect to the charge which thereceptacle is designed to handle, and with respect to the weight of theempty receptacle, that while the weight 52 will act to lift the emptyreceptacle to its upper recciv- 1 ing position, it will not prevent thedescent 'of the receptacle when loaded, the result being that the loadedreceptacle on being released from its weighted lever 35, will swingdownwardly and lift weight 52, and after the contents of the receptacleare discharged, the weight 52 will descend and raise the emptyreceptacle to its receiving position. In other respects this mechanismis the same in operation, and is controlled by the engineer in the samemanner as that first described.

It is desirable in the use of the apparatus in supplying coal tolocomotive tenders, to prevent the operation except by authorizedpersons; to preserve a record of the particular engineer drawing thecoal, well as a record of the quantity of coal delivered. These objectsmay be effected by the employment of a suitable recording mechanism 56,which is mounted on the bin structure within reach of the engineer, asshown in Fig. 1. This recording mechanism is contained within a suitablecase 56-, and is adapted to be operated to record the actions of the tworeceptacles, through the medium of an operating rod 57 operativelyconnected at its lower end with the recordin mechanism and jointed atits upper end to the rear end of an arm 58, extending rearwardly fromand connected with a horizontal rock shaft 59, mounted in hearings onthe front of the bin framing above the receptacles. This rock shaft isprovided with two forwardly extending opera-ting arms 60 and 61extending alongside and adjacent the respective suspending straps 19 and20, in such position that when the receptacles swing downwardly todischarge their contents, the arms will be engaged respectively byfingers 62 and 63 projecting from said straps, by which means the rod 57will be moved upwardly each receptacle descends, and by such operationthe recording mechanism will act to make a record of the number ofcharges delivered.

The mechanism for controlling the stop rods 41 and 42 is adapted to benormally locked aga'unst action by means of a vertical locking rod 64,the lower end of which extends into the casing 56 and the upper end ofwhich extends within a vertical opening in a casting 65 fixed to the binframing adjacent thelocki-ng rod 41. The casting is provided with ahorizontal opening intersecting the vertical opening, and into thishorizontal opening, the outer end of a rod 66 extends, the inner end ofwhich is pivoted to the lever 44 below its axis 45. Normally the lockingrod 64 is held in an elevated position, and is engaged by the outer endof the rod 66, the length of this rod being such that when in.engagement with locking rod 64, lever 44 will be held with its lower endto the right, in which position of the parts the stop rods 41 willengage the upper sides of the levers 35, and the mechanism will belocked against action, the engagement of the end of rod 66 with theupper end of the locking rod 64 preventing the stop rods 41 from beingoperated by cable 48 to release levers 35. The locking rod 64 is adaptedto be released from its elevated locking position by means of a key 68,which is adapted to be inserted through a keyhole 69 in the casing 56 ofthe recording mechanism, the said key acting when inserted and turned,to release the locking rod, which will descend by its weight and itsupper end will be moved free of the'path of the rod 66. In this positionof the parts, the lever 44 controlling the stop rods 41 is free to bemoved by the cable 48 so as to disengage the stop rods from the levers35. The bit of the key 68 is provided with a suitable designating signor numeral to indicate the particular locomotive to which the coal is tobe supplied, and when the key I is turned in the casing and releases thelookrods 41 and 42, and that the stop rods are locked against action torelease the receptacles, by the locking rod 64, and that the lattercannot be released to unlock the parts except by means of a key in thepossession of an authorized person, such as a locomotive engineer. Withthe parts locked in this manner, one of the receptacles will be held inits upper receiving position with its rear gate open and its front doorclosed and it will be filled with coal from the bin. The otherreceptacle will be held in its lower position empty. When a locomotivetender is to be supplied with coal, the engineer inserts his key in thecasing of the recording mechanism and turns the same, with the resultthat the locking rod 64 will be released and will descend, and its upperend will be withdrawn from in front of rod 66. This will release lever44:, and the engineer, by pulling on cable 48, will swing the lower endof lever 44 to the left, which action will swing stop rods 41 and 42outwardly and release the weighted levers 35. The weight of the coal inthe loaded receptacle will, through the medium of the latch on thesuspending strap of the receptacle, swing roller 40 out of the path ofthe latch and the loaded receptacle will descend, which action willclose its rear gate and will open its front discharge door, and thecontents of the receptacle will be discharged. Simultaneously on thedescent of the loaded receptacle, the empty receptacle will be raised toits receiving position, its latch 30 in this action swinging past roller40 on the associated lever 35, and finally will come to rest above, andwill be supported by said roller, and the empty receptacle will be heldin its receiving position, with its rear gate open and its front doorclosed. Goal will now enter this receptacle, and when the weight reachesa certain point, the latch 30 on its suspension strap will force theassociated roller 40 outwardly, and the loaded receptacle beingreleased, will descend to discharge its contents in a manner similar tothe operation of the other receptacle, and these operations will becontinued, with the result that charges of predetermined weight will besuccessively delivered by the two receptacles alternately and in acontinuous and automatic manner. In the actions of the receptacles, therod 57 will be alternately raised and lowered and by this action arecord of the number of charges delivered will be made, and associatedwith the record,.there will be made a record of the designating numeralon the releasing key. IV hen a sufiicient amount of coal has thus beendelivered, the engineer first pulls on cable 49 which will rock lever44: and swing stop rods ll and 4-2 over the outer ends of levers 35,thereby arresting the delivering action of the receptacles. He thenremoves key 62 from the casing of the registering mechanism, and thiswill elevate locking rod 64 and project its upper end in front of theend of rod 66, thereby locking lever 44 in position with the stop rodsin engagement with the levers 35.

In order that the speed of the descent of the loaded receptacles may beregulated and the action cushioned, I provide a fluid cylinder 70,containing a piston 71, carried by a piston rod 72. The cylinder ismounted in an upright position and pivoted at its lower end as at 73 tothe bin framing on a hori zontal axis. The upper end of the piston rodis jointed as at 74 to an extension 75 on the balance lever 25, and inthe opposite ends of the cylinder, relief valves 7 6 are applied. Theconfined air above the piston, when the latter is raised by the descentof receptacle 3, will control the speed of the same and cushion itsaction, and the confined air-below the piston on the descent ofreceptacle l will likewise control its speed and cushion its action.

The coal discharged from the receptacles is received in an apron orchute 77, shown more particularly in Fig. 2, and by the chute isdirected into the locomotive tender. The chute is hinged as at 78 to thebin framing on a horizontal axis so that when the mechanism is not inuse, the chute may swing upwardly out of the way, to a vertical positionin front of the receptacles.

The effect of the cooperative connection of the two receptacles is tocoordinate them in their action, to cause them to move in unison and inopposition with respect to their direction of movement, the doors andgates of the receptacles being likewise coordinated in their actions andbeing coordinately related to the actions of the receptacles, wherebythe receptacles are adapted to ooerate automatically and continuously ine "ecting the successive delivery of predetermined charges of material.

In the foregoing description and accompanying drawings I have disclosedmy invention in the form which I prefer to adopt and which in practicehas been found to answer to a satisfactory degree the ends to beattained. It is manifest, however, that the details of the mechanism maybe variously changed and modified within the skill of the mechanic, andit is further to be understood that the invention is not limited to anyparticular form or construction of the parts except in so far as suchlimitations are specified in the claims.
